Thanks for your answer. No problem to run your code but actually I have the same problem than with patchIntegrate, ie I have to format the file. I would like to get something that I could read more or less directly with gnuplot.

Code:

#Time Massflow
0.02 12.51
0.04 13.20
0.06 15.24

Anyway I will try to change the output format either in your code or either in the patchIntegrate tool.

2.2 - "patchIntegrate" function with field U
It works but the output is a vector and once again I have to process the file before I can use it.

Actually the best solution should be using patchMassFlow but I struggle to understand this warning.

Thanks for help

Don't mind the warning. The SolverInfo-class just tries to determine the properties of the solver you're working with and fails to understand new-school turbulence. But to calculate the massFlow you don't need turbulence so you'll be fine

PS: bug-Report at the mantis of the extend-project would be nice though
